摘要
综合能源系统的脆弱环节辨识对于系统的安全经济运行具有重要意义,复杂网络理论为系统的脆弱环节辨识提供了思路。将应用于电网的带权重的线路介数概念引入到综合能源系统中,并根据综合能源系统特点进行了2点改进。在改进的带权重线路介数的基础上定义了带权重的节点介数。采用基于能源集线器的综合能源系统进行了脆弱性分析,衡量了脆弱环节受到破坏时对系统的影响。通过观察不同攻击策略下系统表现出的脆弱性,验证了所提方法的有效性。
The identification of vulnerable links in integrated energy system is of great significance for its safe and economic operation.Complex network theory provides the idea of determining the vulnerable links.The paper introduces weighted line betweenness applied to power grid into the integrated energy system,and conducts improvement in two aspects based on the characteristics of the integrated energy system.On the basis of the improvement of the weighted line betweenness,the weighted node betweenness is defined.In addition,the paper does the vulnerability analysis of the integrated energy system with energy hub,and assesses the impact on the system when the vulnerable links are damaged.By observing the vulnerability of the system under different attack strategies,the effectiveness of the proposed method is verified.
